"From a clinical point of view, the number of circulating CD34(+) cells was found higher in patients with neovascular AMD, functional properties (colony forming unit and migration properties), however, were found impaired in the patients with severe neovascular AMD (bilateral or larger CNV). 15 So, despite increased peripheral blood levels, it is not clear that the role of stem cells in the choroidal neovascularization process is beneficial or detrimental because of the impaired functional properties. Hence, evaluating of the stem cells’ levels with clinical features of the patients with neovascular type AMD could shed light on the role of stem cells in the choroidal neovascularisation process in AMD. Therefore, the main purposes of this study are to verify previous studies by comparing the peripheral blood stem cell levels in with healthy subjects and to evaluate whether there is any relationship between clinical findings and stem cell levels "
